SPECIFICATION forming part of Letters Patent N o. 705,639, dated July 29, 1902.

Application filed May 14, 1902. Serial No. 107,314. (No model.)

To all whom, it may concern:

Be it known that I, ANDREW J. BOLTON, a citizen of the United States, residing at Pleasant Site, in the county of Franklin and State of Alabama, have invented certain new and useful Improvements in Wind-Wheels; and I do declare the following to be a full, clear, and

exactdescription of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and

to the letters of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in windmills, and especially to a feathering-wheel having series of blades which are presented with their broad faces toward the wind, and when traveling against the wind saidblades are adapted to feather, means being provided to limit the outer throw of the blades and for causing the sameto' move together.

The invention consists, further, in various details of construction and combinations of parts, as will be hereinafter more fully de scribed and then speciically defined in the appended claim.

The invention is illustrated in the accompanying drawings, which, with the letters of reference marked thereon, forma part of this specification, and in which drawings- A Figure l is a perspective view of the windwheel. Fig. 2 is-a planview of one of. the end pieces of the framecarryingthe blades," showing the shoulderswhich hold'the blades in positions at right angles to the wind.

Reference now being hadto the details .of the drawings by letter, A designates a shaft, which may be connected by any suitable` gearing (not shown) to machinery to 4be* driven, and near the upper end of said shaft are fastened the cross-pieces B, C, D, andE, forming, respectively, the"=top IandV bottom` bearing portions forthe movable blades, said; cross-piece B having on its under surfacea shoulder B and a contracted portion inter` mediate the shoulder and adjacent edge of the strip, which is apertured, as at l), to receive the bearing-pins H of the blades H. `It will beobserved that each strip B has two shoul- 5o dered portions arranged on opposite sides of the centralshaft'andin reverse order. The strip O is made similar to the strip B with the shoulder described, and the lower strips D and E are formedlwith the shouldered portions and have apertures K, in which the lower pivotal ends of the blades are j ournaled. Corresponding edges of the blades H are apertured, as at N, and a chain M is connected to each of said blades by being attached to a connection in each aperture, and the inner end of each chainis'fastened to the shaft by means of a pin L or other fastening device.

'These chains are provided for the purpose of limiting the outer throw of the blades, and

Vby means of the chain connections with the edges thereof, and the inner throw of the blades will be held securely against the shoulders at such times as greatest strain is brought to bear upon the blades.

Havingthus fully describedamy invention, what Iiclaim asnew, and desire `to secure by Letters Patent, is-

A wind-wheel comprising a. shaft, cross- `pieces -withshoulders arranged in reverse order on the opposite ends of said cross-pieces, blades having integral pivotal pins along their linner marginal edge journaled in apertures adjacent to said shoulders, anda chain anchored at itsinner end to said shaft and havlingconnection with the swinging edges of said blades to limit their outer throw, as shown and described. .i In testimony whereof I affix my signature `inpresence of two witnesses. ANDREW J. BOLTON.
